Test and Measurement Forum

Hello,
we are having difficulties connecting EL005 logger to EnviroMon software through two GSM modems. Modems are working and connection is established at 9600bps. This was checked with Hyper terminal.
We are also able to establish connection through EnviroMon software. However when data should be read from logger, message dialog Logger not found COM1 TELxxxxxx appears on screen.
If I go to options and check Diagnostics, first message appear connection established succesfull and ther Loger version retrieve failed or even program will crash

If logger is connected directly to PC everything is working perfectly.

Many thanks for answer

Hi Michael,
yes we have enabled telephone+modem option. And As I indicated in my first post, first we get a message connection established. However, when data should be transmited from logger to PC, we get message Logger not found.
If I listen at serial port, between logger and GSM modem. I see that GSM modem receives two rings then it wrote message CONNECT 9600BPS.

Hi,
to which address should I send requested files. My email is
erazem_dot_polutnik_at_fs_dot_uni-lj_dot_si.
I doubt there is problem in modems as I'm able to connect two computers with these modems and transfer a file in both directions.
Also EnviroMon indicates connection is established.

In New Hampshire, What MHz does the GSM Network Use? I bought a CECT a380i smart phone because it was GSM 900/1800/1900, not realizing some GSM like ATT in the US were 850. Should I be alright when I get this activated?
